Is Leaving Your Car Running Unattended Legal in Ireland After the 2026 Regulatory Updates?

No, leaving a car running unattended in Ireland is illegal under the Road Traffic Acts, with exceptions only for specific scenarios like defrosting or warming the engine in extreme cold. The Road Safety Authority and An Garda Síochána enforce this, with fines up to €120 and potential penalty points. Local authorities may impose additional restrictions in high-risk areas.


Key Regulations for Leaving Your Car Running Unattended in Ireland

  • Road Traffic Act 1961 (Section 40): Prohibits leaving a vehicle unattended while the engine is running, unless the driver remains within sight and control of the vehicle. Violations carry a fixed charge notice of €60, rising to €120 if unpaid within 28 days.
  • Gardaí Discretionary Powers: Officers may issue penalty points (2) for repeat offences under the Road Traffic (Amendment) Act 2018, particularly in urban areas like Dublin or Cork where theft risks are elevated.
  • Local Authority Bylaws: Certain councils (e.g., Dublin City Council) enforce stricter controls in designated zones, such as near schools or public transport hubs, where idling is banned entirely under the Air Pollution Act 1987 (Amended 2023).

Enforcement has intensified ahead of the 2026 EU Clean Air Directive, with local authorities deploying ANPR cameras to monitor idling hotspots. Drivers should note that even brief unattended engine running—such as during a quick errand—constitutes a breach. Exemptions apply solely to emergency services or vehicles with disabled drivers requiring engine operation for mobility aids.
